Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles

NAACP Interview Synthesis For over 100 years our country’s chief social equality association has battled for human rights‚ voting rights‚ monetary rights. The NAACP’s expressed objective was to work to secure the rights ensured in the thirteenth‚ fourteenth and fifteenth revisions to the United States Constitution. From its initiation in 1909 until today the NAACP keeps on pushing forward in political‚ financial‚ and social issues. Today the NAACP has multiple different programs and sub-organizations

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

Synthesis Paper for Langston Hughes Introduction: Love is often regarded as an emotion that invokes extreme joy‚ hope and excitement. For example‚ Romeo and Juliet were a young couple who were so excited and hopeful about their love that they were willing to do anything to be together. However‚ there is another side to the feeling we call love that isn’t so joyous. The other‚ darker side of love is expressed by three Langston Hughes poem which show us the heart-break‚ the abandonment and the desperation

towards the Now phase of perception. He quickly points out that immanent objects only have ". . . one possible way to be given in the original in every Now . . ." which means during the duration of an experience of an immanent object‚ a color for example‚ the object is completely determined and the distinction between appearing and what appears is collapsed(ACPAC553). The reverse is true in the case of external perceptions of transcendent objects. As Husserl states‚ ". . . the spatial object has

was 59.23%. The characteristics of the synthesized ester were liquid‚ oily‚ and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic

Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

Media Argument Synthesis A man stumbles out of a bar and digs through the junk in his pocket to find his keys. He scratches the door of his car while trying to unlock it. He proceeds to get in his car and drive home. Five days later‚ here he sits…in a cemetery. He didn’t know when enough was enough and a bad decision was made based on his lack of knowing when to stop.
